Installed successfully but require 'nn' failed?

[wangg12]

I cloned this repo and built with install.sh. Then I typed require 'nn' in th shell, but got the following error:

/net/wanggu/torch/install/share/lua/5.1/trepl/init.lua:384: /net/wanggu/torch/install/share/lua/5.1/trepl/init.lua:384: /home/wanggu/.luarocks/share/lua/5.1/nn/test.lua:12: attempt to call field 'TestSuite' (a nil value)

My system is Ubuntu 14.04. My cuda version is 7.5 and my cudnn version is v4-prod.

Anyone can give me a hand?

Do

luarocks install torch

See if that fixes things

@soumith luarocks install torch is ok, but the error still exists.

I tried clean.sh update.sh and reinstall. And I removed some packages in ·.local·. Then somehow it was solved. Maybe it is related to confusion between the local packages and the packages in where torch is installed.
